BILLING WITH TAXONOMY CODES AND ZIP+4
Providers are reminded that they should not bill with a taxonomy code in the 2000A PRV03 segment of the 837 unless MassHealth has directed them to include one. Listing a taxonomy code may cause claims to deny for error 1945 - BILLING PROVIDER NPI IS MAPPED TO MULTI SERV LOC when the NPI cannot be crosswalked to the correct MassHealth Provider ID/Service Location (PID/SL).
MassHealth has assigned a unique taxonomy code to each provider type and does not allow providers to self-attest taxonomy codes. MassHealth will not update a provider file with a taxonomy code if requested. There are times when MassHealth will assign a taxonomy code to a PID/SL to allow an NPI to crosswalk to the PID/SL.
Providers must also be sure to use the current USPS Zip+4 code on their claim file. Billing with a dummy Zip+4 of 9998 or an incorrect Zip+4 may cause claims to deny for error 1945 - BILLING PROVIDER NPI IS MAPPED TO MULTI SERV LOC when the NPI cannot be crosswalked to the correct MassHealth PID/SL.
If you have questions, please contact MassHealth at provider@masshealthquestions.com or (800) 841-2900.
